This invention relates to explosives and more particularly to blasting compounds.

The object of the invention is to provide a composition of this character which may be quickly manufactured without resorting to the use of expensive machinery and dangerous manipulation and which when made will not explode, by friction, will not explode in open air, and may be extinguished should it become accidentally ignitet In the explosive composition comprising this invention, the following ingredients in or about the proportions stated, are employed:

Yellow wax 13% Son stock (seponifieble fatty material) 7 ".1 Sn] cur 21% Niter -1 n 11% Potassium ehloratencfl ""2270 Nitro-stareh .4 26% I do not confine myself to the win-t proportion: of the ingredients above stated as such proportions may be varied lN'POl'dlTlg to the strength of the explosive required and the use of snid explosive is not confined to blasting purposes.

In inm'uifacturing the wax and son p SlOt'lt are and lltiilt'tl to about 140 powder the yellow plum-d III a kettle I m re or less.

' siuin chlorate and 261),; of nitro-stzirrh, these two ingredients being substantial equivalents and the one which is the rlieupest is preferubl used.

The ye low wax and sea stock serve to prevent friction between he active ingredients so that jurring of the powder will not cause it to ignite or explode and should it accidentallyignite, it may be extinguished in the ordinary manner. In order to cause this powder to explode it is neressury that it he confined and ignited.

:i'lii'itfg to the fact that this powder is not: explosive until confined und ignitrd, no precugution needl e taken in lmndlingit.
